Code P0301; Misfire in Cylinder 1
Hey guys I had this code show up before so I replaced all the sparkplugs and wires and my car was fine for a day but then started misfiring again and like 2 weeks later the "Check Engine" light came on again and it was the same code! So it can be the coil pack or fuel injector but I want to know how can I check to be sure and also could it be another problem?? There is a crack/leak in my exhaust so you hear air escaping from where the cats should be at. I'm not sure if that could be the cause of all this?
